21.3 NAT Setup
Use the address mapping sets menus and submenus to create the mapping table used to assign
global addresses to computers on the LAN.
Set 255 is used for SUA. When you select Full
Feature
in menu 4 or 11.3, the SMT will use Set 1 . When you select
SUA Only
, the SMT
will use the pre-configured Set 255 (read only).
The server set is a list of LAN servers mapped to external ports. To use this set, a server rule
must be set up inside the NAT address mapping set. Please see the
section on port forwarding
in the chapter on NAT web configurator screens for further information on these menus. To
configure NAT, enter 15 from the main menu to bring up the following screen.
